TALKING-MACHINE REGISTER.

Application filed August 10, 1920.

'1 '0 all to ham it may concern:

Be it known that I, James P. CAREY, a citizen of the United States, residing at Brooklyn, in the county of Kings and Stateof New York, have invented certain new and useful Improvements in Talking-Machine Registers, of which the following is aspecification.

This invention relates to a talking machine register and has for its principal object the production of a simple and efficient signal so as to prevent the spring of any talking machine from being wound too tightly and thus being broken or having an undue strain put thereon. This register will indicate the number of turns which will be required of the crank in order to wind the spring to the desired tension.

Another object of the invention is to provide an audible signal which will warn the operator. when the spring is about to reach the desired tension if he should not be looking at the indicator dial.

A still further object of the invention is to produce a register of this nature by providing a device which will be extremely simple, durable and inexpensive in construction, one which is efficient and reliable in operation and well adapted to the purpose for which it is desired.

With these and numerous other objects in view, the invention resides in certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings Figure 1 is a fragmentary perspective view of a phonograph showing my invention attached thereto, and

Fig. 2 is a section taken through the phonograph showing the invention in side elevation.

Referring to the drawing in detail it will be seen that 1 indicates the box within which the operating means for the phonograph is mounted and may be of any conventional construction. As shown in Fig. 2, my device is mounted within the box 1 and consists of a sleeve 2 which forms a bearing for a stub extending longitudinally from the worm gear 3. The other end of the worm gear is hollowed out so as to provide 1 an elongated square opening for receiving the square portions 4 of the shaft 5. The relative large beveled gear 6 1s fixedly Specification of Letters Patent.

is provided thereon a squared portion 12 and thus it will be seen that when this squared portion is in engagement with the square bore of the sleeve 11 the shaft 5 will be rotated when the gear 6 is rotated. The gear wheel 13 is carried upon the shaft 14: extending from the crank 15 which used for winding the spring in a well known manner.

The shifting lever 16 is pivotally mounted within the slot 17 provided in the top portion of the box 1 and is provided with the bifurcated portion 18 at its inner end upon the terminals of which are provided inwardly extending lugs which ride in the groove 19 of the collar 20 which is fixedly attached to the shaft 5. A gear wheel 21 is mounted upon the shaft 5 for meshing with the gear wheel 13 when desired. Thus it will. be seen that by referring to Fig. 2 that when the collar 20 is shifted toward the right the gear wheel 21 will be in mesh with the gear wheel 13 while the squared portion 12 of the shaft 5 will be out of engagement with the square bore of the sleeve 11 and thus when the crank 15 is wound the shaft 5 will be rotated thereby. On the other hand when the collar 20 is shifted to the left the gear wheel 21 will be out of mesh with the gear wheel 13 while the squared portion 12 of the shank 5 will be in engagement with the square bore of the sleeve 11 and thus the shaft 5 will be rotated when the relatively large gear wheel 6 is in motion.

Mounted upon the worm gear 3 is the cylinder 22 which is provided with a bore having an internal worm for meshing with the worm gear 3. An arm 23 extends upwardly from the cylinder 22 and moves in the slot 24. Upon the upper end of the arm 23 is the finger 25 which will operate the indicating dial 26 in any preferred manner and intermediate the ends of the arm 23 there is mounted the finger 26 for operating the audible signal 27 which may also be of any preferred construction. Since the dial 2G and audible signal 27 may be of any conventional form as may be desired it is not thought necessary to here illustrate same except diagrammatically as shown in the drawing. A stop arm 28 extends from the side wall of the box 1 underneath the worm gear 3 provided with the lip 29 at its end so as to preventthe movement of the cylinder 22 to the left when same has arrived at the end of the worm gear 3. hen the record disk 8 is rotating it will cause the cylinder 22 to travel toward the left of Fig. 2 provided of course the squared portion 12 is in engagement with the square bore of the sleeve 11 and when the gear 21 is in mesh with the gear 13 and the crank 15 is operated this cylinder 22 will move toward the right of Fig. 2. Thus it will be seen that the audible signal 27 may be set as may be necessary and that the dial 26 may be arranged so as to indicate the number of turns it will be necessary to operate the crank 15 so as to wind the spring to the desired tension.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the device will be readily understood without a more extended explanation. As numerous changes in form, proportion, and in the minor details of construction may be resorted to without departing from the spirit of this invention I do not wish to be limited to the construction herein shown and described other than as claimed.

Having thus described my invention what I claim as new is 1. In combination, a winding mechanism, an operating mechanism therefor, a shaft having a square portion at one end and a second square portion a distance from the other end, a worm gear having a square bore for receiving the first mentioned square portion. a cylinder mounted on the worm gear, means in the cylinder for engaging the worm gear, and means for shifting the shaft into engagement with the winding; mechanism or the operating mechanism for indicating the number of revolutions made thereby.

2. In combination, a winding mechanism, an operating mechanism therefor, a shaft having a square portion at one end and a second square portion at a distance from the other end, a worm gear having a square bore for receiving the first square portion, means for shifting the shaft into engagement with the winding mechanism or the operating mechanism for indicating the number of revolutions thereof, and means mounted upon the worm gear or operating an indicating dial and an audible signal all in the manner and for the purpose specified.

In testimony whereof I atiix my signature in presence of two witnesses.
